Date: Wed, 23 Sep 2026 13:15:19 +0200 Message-ID: <20260923111518.310430-8-dev@lankhorst.se> X-Mailer: git-send-email 2.55.0 MIME-Version: 1.0 Content-Transfer-Encoding: 8bit X-BeenThere: intel-gfx@lists.freedesktop.org X-Mailman-Version: 2.1.29 Precedence: list List-Id: Intel graphics driver community testing & development List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Errors-To: intel-gfx-bounces@lists.freedesktop.org Sender: "Intel-gfx" This series has dropped 'drm/i915/gt: Use signalers_lock to prevent starvation of irq_work.', but otherwise includes all fixes I have created so far to make the core i915 module work correctly on PREEMPT_RT. I'm hoping by reducing the delta, the remaining patches will become easier to review and accept. A major patch series with nearly 30 patches over the entire code is harder to review and accept than a few isolated series targeting specific parts of the driver. Maarten Lankhorst (3): drm/i915/gt: Fix selftests on PREEMPT_RT drm/i915/gt: Set stop_timeout() correctly on PREEMPT-RT drm/i915: Use sleeping selftests for igt_atomic on PREEMPT_RT Sebastian Andrzej Siewior (3): drm/i915/gt: Use spin_lock_irq() instead of local_irq_disable() + spin_lock() drm/i915: Drop the irqs_disabled() check drm/i915/guc: Consider also RCU depth in busy loop. drivers/gpu/drm/i915/gt/intel_engine_cs.c | 2 +- .../drm/i915/gt/intel_execlists_submission.c | 17 +++++------------ drivers/gpu/drm/i915/gt/selftest_engine_pm.c | 8 ++++---- drivers/gpu/drm/i915/gt/uc/intel_guc.h | 2 +- drivers/gpu/drm/i915/i915_request.c | 2 -- drivers/gpu/drm/i915/selftests/igt_atomic.c | 7 +++++++ 6 files changed, 18 insertions(+), 20 deletions(-) -- 2.55.0
